About Chronological Age
Chronological age is a precise measure of a person's age in years, months, and days. It's particularly important for educational and psychological assessments, where age-normed comparisons are made.
Pearson assessments typically require exact age calculation for accurate interpretation of standardized test scores, particularly for developmental assessments.
